Eigenvalues and eigenlines/matrices

Please help me!

(a) Find the eigenvalues and eigenlines of the following matrix A. For each eigenvalue, give an eigenvector with integer components. A = (b) Express the matrix A in the form , where D is a diagonal matrix. You should evaluate P and .(c) Use part (b) to find the matrix . (d) Calculate the second and third points of the iteration sequence with recurrence relation = (n = 0,1,2,3...) for each of the following initial points.(i) (-2, -4)(ii) (0, 1)
